| 摘 要： | 提出了一种新型的应用于2.4/5GHz蓝牙和无线局域网的双频内置平面倒F天线。该天线结构紧凑,可以方便地植入无线通信设备中,有较强的实用性。通过加载F形槽和阶梯形槽使天线能够满足无线局域网中小型化双频天线的技术要求。天线在蓝牙频段阻抗带宽达到300MHz(2.21~2.51GHz),在无线局域网频段阻抗带宽达到1070MHz(4.95~6.02GHz),辐射方向图表明该天线全向性能较好,增益在3.1~6.7dBi范围内。

| Abstract: | A novel compact dual-frequency planar inverted-F antenna for 2.4/5 GHz bluetooth and WLAN applications is presented.The antenna owns the feature of compact operation and can be easily integrated into most wireless communication equipments.The F-shaped slot and ladder notches configuration is employed to satisfy the technical requirements of the WLAN antennas.The antenna achieves an impedance bandwidth of 300 MHz(2.21~2.51 GHz) in bluetooth band and 1 070 MHz(4.95~6.02 GHz) in WLAN band.This antenna is characterized by its omni-directional radiation pattern.The gain of the antenna changes from 3.1 dBi to 6.7 dBi. |
